This accidentally worked as long as the Sound CPU program did not do meaningful stack manipulation. Indeed, none of the Sound CPU programs I have written so far do anything with the stack. Despite this "accidentally working" on real hardware, mednafen's m68k emulation appears to "stall" the Sound CPU when the stack pointer wraps around to a memory that does not exist. This table was originally written when I was first learning about the Saturn "sound block" memory map. I did not know exactly how large the installed sound RAM was, as the manual mentions 8Mbit, 4Mbit, and 1Mbit as being possibilities. Now that I know the production Saturns have 4Mbit installed, I am able to come up with a reasonable value for the stack pointer.
